IMPROVEMENT IN WlCK-BURNERS FOR HEATING AND CUOKENG.

Specification forming part of Letters Patent No. 573%}, dated September11, 1866.

To all whom it may concern:

Be it known that I, H. W. DOPP, of Buffalo, in the county of Erie, inthe State of New York, have invented an Improvement in Wick- Burners forthe Combustion of Inflammable Oils for Heating and Cooking Purposes; andI do hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

Figure I is a perspective view of the workin g model. Fig. 11 is apartial perspective view and partial sectional cut of the burner,

showing its various parts and connections.

A is the oil-reservoir.

B is a small feed-pipe leading the oil from A to the wick, one end beingin connection With oil-reservoir A, and the other end with the bottom ofthe wick-tube.

O is the bottom or base plate of air-tube D, wick-tube E, andsteam-retort H. It likewise forms part of a damper for regulating theamount of atmosphere which passes through a number of holes in saidplate.

D is a tube attachedto O, and surrounding wick-tube E, leaving a spacebetween the two tubes for thesupply of atmosphere to the outside of theflame, obtained from a round wick in wick-tube E. It is also perforatedat the lower end.

D is a space surrounded by the wick-tube E, for the admission ofatmosphere, to be'supplied to the inner surface of the flame from wickin wick-tube E.

E E are two tubes, one within the other, secured to G, both togetherconstituting the wicktube.

F is a damper of circular form, having a number of holes through it, thesame corresponding with the holes in and through the base-plate O. Thehub of this damper is of cam shape, as clearly shown in Fig. I. It isattached to under side of 0. It is so adjusted that a quarterrevolulioneither way produces the results for which it is designed; thus, first,cutting off the entire supply of atmosphere from the center of theflame; also, alarge supply of atmosphere is cut off from the outside ofthe flame; second, for letting on a supply of superheated steam into thecenter of the flame, the purpose of which latter is hereinafter morefully explained.

G is a cap. Its rim is of a cam shape, corresponding with the hub of F.It is secured to a small rod, I, by a nut and beneath O and F. It isconnected with (J in such a manner as to prevent it from turning around,and at the same time to receive an up-and-down motion whenever thedamper shall be opened or shut.

His a retort for generating superheated steam. It is secured at thelower end to O, and at the upper end to acopper generator, L. It passesthrough the center of the space within the round wick-tube E.

I is a small rod secured at the lower end to cap G by means of a smallnut. It runs up through the center of O and a cork packing, which issecured in C; also, in and through the center of retort H up to the topof generator L, when it shuts oif the supply of steam whenever thedamper F is opened, and lets on a supply of steam when the damper F isturned shut. A spiral spring surrounds and acts upon this rod, by meansof which it is forced shut. The action of cam F and G opens it. Theupper end of this rod is of a conical, pointed, valve shape, which fitsinto a small orifice in and through the center of generator L, as seenin Fig. H.

K K are two small rods attached to a ring inside of wick-tube. The wick,being secured to this ring, is raised or lowered by operating theserods. They are kept from leaking or producing leakage by means of a corkpacking in the bottom of wick-tube E, through which they pass.

L is the top of retort and generator, provided with a small orifice inits center, through which the superheated steam makes its exit, and alsowith three prongs projected upward into the center of the flame, bymeans of which heat is absorbed and conducted to the retort H.

M is a'cylinder placed on the top of air-tube D, so that the flameobtained from the wick will pass through its center. It createssufficient draft when the damper F is opened to supply a moderatelysized flame with the requisite amount of atmosphere, and conducts theheat obtained from said flame under the cooking-utensil placed on thetop of a stove, used in conjunction with this burner. It is constructedwith special reference to guard against the loss of heat fromradiation,by constructing a double cylinder, leaving space N, which maybe filled either by a non-conductor or left filled with air.

N is a window in cylinder M for ascertaining the size of flame.

()is afeedpipe conducting water to retort H.

This apparatus is intended to burn any inflammable oil with or withoutthe aid of steampressure.

Steam is to be applied when a large flame or increased heat is desired,and when applied will be operated as follows:

The damper F should be first opened. Rainwater should then be filledinto the water-reservoir at an altitude of two or more feet above theorifice in the generator L. Oil is then to be filled into oil-reservoirA, which should stand on a level with the wick. Now, the cylinder M islifted off from D, the wick raised and ignited. Cylinder M is now to bereplaced. The apparatus is now burning without the aid ofsteam-pressure. All the atmosphere needed is supplied by the action ofthe chimney or cylinder M. After it has burned for a few minutes a largeflame can be obtained by simply raising the wick a little higher, andthen shutting the damper F, which was before opened, thus cutting offthe supply of atmosphere entirely from the inside of the flame, causingit to draw together to a long cone. At the same time that the damper shnts, a current of superheated steam is turned on, which makes its exitout of the small orifice in generator L, and right into the center ofthe long conical flame. By this means a flame is produced like that ofan ordinary blow-pipe-larger, but of the same intensity and combustion.The necessary amount of atmosphere now passes through the perforatedpart of tube D, and up to the flame, where it mingles with the gasesfrom the wick and superheated steam. To extinguish the apparatus thedamper is to be shut and the wick lowered.

I claim- 1. The application of a current of steam or water vapor, incombination with a wickburner, for burning any inflammable oil forcooking and heating purposes, substantially in the manner hereindescribed.

2. The mode of raising and lowering the wick, as described.

3. The employment of cylinder M, in combination with a stove for cookingor heating purposes, and wick burner or burners, so constructed that thesame shall serve to create a draft sufficient to supply the flame withatmosphere, and at the same time conduct the heat directly to thecookingutensils used, as set forth.

4. Oonstructin g the cylinder M so as to prevent the loss of heatbyradiation, as shown in Fig. II, and described.

5. The window N, in combination with cylinder M.
